执行器JMS运行状况检查通过Java配置返回假阳性

我遇到了一个问题,即使我的路由可以连接并向JMS生成消息,但对于JMS运行状况来说,执行器探针仍会失败。简而言之,Actuator表示它已关闭但正在运行。

技术堆栈和技术说明:

  • 春季启动:2.3.1。发布
  • 骆驼:3.4.1
  • Artemis:2.11.0
  • Artemis已设置为使用用户名和密码(artemis / artemis)。
  • org.apache.activemq.artemis.jms.client.ActiveMQConnectionFactory用于连接工厂。

我的路线就像筹码一样简单:

  <route id="timer-cluster-producer-route">
            <from uri="timer:producer-ticker?delay=5000"/>
          
            <setBody>
                <groovy>
                    result = ["Name":"Johnny"]
                </groovy>
            </setBody>
            <marshal>
                <json library="Jackson"/>
            </marshal>
            <to uri="ref:jms-producer-cluster-event" />
   </route>

基于XML的Artemis配置

使用Spring-boot支持基于Java的配置时,我正忙于相应地迁移XML bean。因此,我将一个有效的bean.xml文件粘贴到项目中并启动了路由,我可以发送消息并运行状况检查返回OK

        <property name="configuration" ref="jmsConfig" />
    </bean>-->
    

</beans>


春季启动自动(黑色)魔术配置

然后,我使用了application.yaml文件通过使用this method来配置artemis连接,如Spring-boot文档中所述。当我的application.yaml文件包含以下配置时,这也起作用:

artemis:
  user: artemis
  host: localhost
  password: artemis
  pool:
    max-sessions-per-connection: 500
    enabled: true
    max-connections: 16

这就像一种魅力。

勇敢尝试Java配置。

所以我接着去淘金,尝试了如下所示的基于Java的配置:

@SpringBootApplication
@ImportResource("classpath:/camel/camel.xml")
public class ClusterProducerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ClusterProducerApplication.class, args);
    }
    @Bean
    public JmsComponent jms() throws JMSException {
        // Create the connectionfactory which will be used to connect to Artemis
        ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory();
        cf.setBrokerURL("tcp://localhost:61616");
        cf.setUser("artemis");
        cf.setPassword("artemis");

        //Create connection pool using connection factory
        PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory();
        pooledConnectionFactory.setMaxConnections(2);
        pooledConnectionFactory.setConnectionFactory(cf);

        //Create configuration which uses connection factory
        JmsConfiguration jmsConfiguration = new JmsConfiguration();
        jmsConfiguration.setConcurrentConsumers(2);
        jmsConfiguration.setArtemisStreamingEnabled(true);
        jmsConfiguration.setConnectionFactory(pooledConnectionFactory);

        // Create the Camel JMS component and wire it to our Artemis configuration
        JmsComponent jms = new JmsComponent();
        jms.setConfiguration(jmsConfiguration);
        return jms;
    }
}

因此,当骆驼启动时,我会在启动时看到以下警告:

020-07-28 12:33:38.631  WARN 25329 --- [)-192.168.1.158] o.s.boot.actuate.jms.JmsHealthIndicator  : JMS health check failed

javax.jms.JMSSecurityException: AMQ229031: Unable to validate user from /127.0.0.1:42028. Username: null; SSL certificate subject DN: unavailable

5秒延迟后,计时器开始计时并生成消息。我登录到Artemis控制台,可以浏览消息并看到它们正在创建。但是,当我对执行器的运行状况进行检查时,会看到以下内容:

 "jms": {
            "status": "DOWN",
            "details": {
                "error": "javax.jms.JMSSecurityException: AMQ229031: Unable to validate user from /127.0.0.1:42816. Username: null; SSL certificate subject DN: unavailable"
            }
        },

这对我来说似乎是个很大的错误。

有关连接池实现的观察。

我注意到AMQ连接池已移入以下Maven依赖项:

<dependency>
  <groupId>org.messaginghub</groupId>
  <artifactId>pooled-jms</artifactId>
</dependency>

我想让我也尝试一下。它显示了与上面概述的行为相同的行为,还有另外一件有趣的事情。在将org.messaginghub.pooled-jms用作连接池时(也由spring-boot文档推荐),以下内容将在启动时记录。

2020-07-28 12:41:37.255  INFO 26668 --- [           main] o.m.pooled.jms.JmsPoolConnectionFactory  : JMS ConnectionFactory on classpath is not a JMS 2.0+ version.

根据the official repo,该连接器符合JMS 2.0标准。

快速摘要: 通过Java配置JMS组件时,执行器似乎没有获取连接工厂的凭据。通过使用spring-boot application.yaml配置,目前可以解决此问题,但它限制了您在Camel上配置JMS客户端的方式。

1 个答案:

答案 0 :(得分:0)

因此,在经过一些挖掘并与GitHub上的Spring-boot人员联系后,我发现了问题所在。使用Java配置时,我正在使用连接工厂配置Camel的JMS组件。但是,Spring-boot完全没有意识到这一点,因为它是Camel组件。因此,JMS使用的连接工厂需要暴露于Spring-boot才能正常工作。

修复相对简单。参见下面的代码:

@Configuration
public class ApplicationConfiguration {
    private ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory();
    @Bean
    public JmsComponent jms() throws JMSException {
        // Create the connectionfactory which will be used to connect to Artemis
        cf.setBrokerURL("tcp://localhost:61616");
        cf.setUser("artemis");
        cf.setPassword("artemis");
        
        // Setup Connection pooling
        PooledConnectionFactory pooledConnectionFactory = new PooledConnectionFactory();
        pooledConnectionFactory.setMaxConnections(2);
        pooledConnectionFactory.setConnectionFactory(cf);
        JmsConfiguration jmsConfiguration = new JmsConfiguration();
        jmsConfiguration.setConcurrentConsumers(2);
        jmsConfiguration.setArtemisStreamingEnabled(true);
        jmsConfiguration.setConnectionFactory(pooledConnectionFactory);
        // Create the Camel JMS component and wire it to our Artemis connectionfactory
        JmsComponent jms = new JmsComponent();
        jms.setConfiguration(jmsConfiguration);
        return jms;
    }
    /*
       This line will expose the connection factory to Spring-boot.
    */
    @Bean
    public ConnectionFactory jmsConnectionFactory() {
        return cf;
    }
}
